I could never write female characters when I started out. And when I met Diane Keaton, and got friendly with her, and lived with her for a few years, I became so enamoured of her, I just fell in love with her. I became so enamoured of her as a human being, so in awe of her, that I started to write for her. I wrote Annie Hall for her, and then after that I could almost only write for women characters.
